Dear Mr/Ms Muthen,
I'm estimating a 120x120 covariance matrix from continuous raw data (sample size 1000) using a 64-bit version of MPlus on a 64-bit operating system. However I get the 'not enough memory space..' error. How is this possible?
Best,
Sanja

Or is 14520 parameters (it's a 2-group analysis) just impossible to estimate even with the 8 terabytes of memory? What would (approximately) be the largest number of variables I could include in this analyses? E.g., for a 2-group analyses of 60 variables, I would have 3660 parameters to estimate. Is that doable?

Please send the input, data, and your license number to support@statmodel.com. This does not sound unreasonable but I need to see the details.

It was a problem in my model, I just fixed it and it works. Thanks a lot! Sanja
